Sounds like a post being made by a spambot, which will make several inane but "safe" posts in order to ensure it can post on a moderated list. And then, spam the list for porn or home loan schemes.

Incidental, guys, the FBI (honest!) tells me that a lot of those "really great" offers you get as spam are really soliciting personal information and credit card information, which is then sold to international organized crime. The cheap home loans and the software and plasma TV's at 80% off list, never will happen.
